      (b)    The incorporation of all elements of any applicable areawide water quality management plans, basin plans and statewide land use plans;

      (c)    Total maximum daily load for pollutants;

      (a)    The department shall approve or reject proposed revisions to the areawide water quality management plan for the area consisting of Dane County. The department shall base a decision under this paragraph on whether the proposed revision complies with the water quality standards under s. 281.15. The department may place conditions on its approval of a proposed revision to the plan.

      (b)    The department, or a person contracting with the department under par. (f), may not require information concerning a proposed revision to the areawide water quality management plan for the area consisting of Dane County other than information that is reasonably necessary to determine whether the proposed revision complies with water quality standards under s. 281.15.

      (c)   

         1.    Except as provided under subd. 2., the department shall approve or reject a proposed revision to the areawide water quality management plan for the area consisting of Dane County no later than the 90th day after the day on which the department, or a person contracting with the department under par. (f), receives the formal application for the proposed revision, including a letter from the applicant certifying that the proposed revision is consistent with water quality standards and information supporting the certification. If the department determines that the application is incomplete, the department shall notify the applicant in writing within 10 days after the department receives the application and may make only one request for additional information during the 90-day period under this subdivision.

         2.    If the department does not approve or reject a proposed revision to the areawide water quality management plan by the 90th day after the day on which the request is received, the revision is approved on the 120th day after the day on which the department receives the formal application for the revision, unless the department petitions the circuit court for an order extending the time to act on the proposed revision. The court may issue an order extending the time for the department to act on the proposed revision by an amount it determines is reasonable.

      (e)    The department may not contract with Dane County or any of its subunits, including the Dane County lakes and watershed commission, to provide advisory services relating to the review of proposed revisions to the areawide water quality management plan for the area consisting of Dane County.

      (f)    Except as provided in par. (e), the department may contract with a regional planning commission or other entity to provide advisory services relating to the review of proposed revisions to the areawide water quality management plan for the area consisting of Dane County, but the department may not delegate its authority to approve or reject proposed revisions. The deadline under par. (c) 1. is not affected by a contract entered into under this paragraph.

   (2)   When the department receives for review or prepares a new plan under sub. (1) or a revision to a plan under sub. (1) that includes a proposal to return water transferred from the Great Lakes basin to the source watershed through a stream tributary to one of the Great Lakes, the department shall provide notice of the plan or revision to the governing body of each city, village, and town through which the stream flows or that is adjacent to the stream downstream from the point at which the water would enter the stream.
